SPECIFICATION forming part of Letters Patent No. 272,777, datedebruary20, 1888.

Application tiled December 12, 1881. (No model.)-

To all whom it may concern Be it known that 1, LYON P. ROSS, a citizenot the United States, residing in the city of Rockford, in the countyotVinnebago and State ot' Illinois, have invented a new and usefulCabinet Folding Desk, of which the following is a specification.

My invention Vrelates to desks mainly employed in offices in thetransaction of business; and its object is to produce a desk of greatcapacity, containing a great variety and large number of compartments insmall compass, and capable of use as a sitting and standing desk. Tothis end I have designed and c0nstructed the cabinet desk represented inthe accompanying drawings, in which- Figure l is an isometricalrepresentation of my improved cabinet desk iu its closed position and inthe form to be used as a standingdesk. Fig. 2 is an isometricalrepresentation ot' the desk with the upper portion anda por' tion of oneof the ends cut away to reveal the locking mechanism, and Fig. 3 is anisometrical representation of' a portion of the vertical post of thelocking mechanism.

The lower portion of my improved cabinetdesk is substantially the sameas some desks to be found in the trade, consisting of end portions ofpedestal form, one ot' which, as at A. is fitted with drawers (t, b, c,and d, and the pedestal B is mainly ot' closet form, the interior ofwhich may be fitted in any convenient manner with drawers or withvertical or transverse compartments, and its front is titted with adoor, e, having-a suitable hingesupport. This pedestal is also providedAwith a drawer, f.

u These pedestals are separated a proper distance,having their rearportions connected by a central recessed closet, (l, and its recessedfront provided with a suitable door, h, mounted to swingon its hingedconnection. Tliein terior of this closet may be iitted in any convenientmanner with drawers, transverse or vertical divisions, or both, toseparate it into divisible compartments. The pedestals are connected ontheir front edge' by means of a suitable bar, h', which spans thecentral recess between them and overlaps their front edges.

At It are transverse bars, having their front ends suitably joined tothe rear edge of the front bar, h', from which they extend rearward,

having their rear ends suitably fixed to arear bar or to the back ot thedesk.

At t' is represented a drawer placed in the center, between the endpedestas and immedi? ately under the draw writing-table.

Atkare represented groovedslideways,tixed in a suitable verticalposition to the inner side tion to overlap the upper edge of the rearend of the drawers when slid down, as represented in the dotted lines.The upper ends of these vertical slides are connected by means ofastiltable horizontal bar, 79".

At Z are represented spiral springs placed at proper intervals under thehorizontal 'bar s', employed to support the slides in their elevatedposition, but in such a manner asto permit them to be depressed to lockthe drawers when closed.

At l are represented bars having their forward ends pivoted at L to theedge portion of the transverse bars la, from which point they extendrearward, and are connected to the under side ofthe horizontal bar ina'manner to permit a free vertical movement of the locking mechanism.

At D are represented the end portions of the writing-table, whichare`fixed to the pedestals on the outer ends ot' the cabinet, having theiredge portions projecting beyond the pedestal, on the ends and frontthereof.

At E is represented the draw writingtabl'e, fitted to slide back andforth between its fixed end portions, and on its rear edg'e is theuprising portion m, to be carried with the movements ofthe draw-table.The front edge ot' this dr'awtable and the front and end edge portionsof its fixed ends are of round or other suitable form, and are thecrowning member ofthe pedestal or lower portion of the cabinet. By this.construction it will be seen that the inward or rearward slidingmovement ot' the table will operate to depress the pivoted levers l',which, by meansot their connection with the horizontal bar c", willdepress the slide barsv la', to which it is fixed, causing thehookclasps lc, fixed to the vertical sliding bars, to engage the IOOrear ends of the drawers to lock them in their closed position, and theforward movement of the draw-table will relieve the pivoted levers andpermit the vertical slides to rise under the action of the spiralsprings to unlock the drawers.

I am aware that folding desks have been constructed in which the topsection was folded over and against the fixed section, therebycompleting an even dat top for use when closed, and also in Whichlocking devices have been used and operated by the downward action of arolling top. I therefore do not claim such construction, broadly, myinvention relating to au improved form of the top section, and also toimprovements in the locking devices, in which the draw writing-table, byan independent horizontal movement, operates the locking devices.

What I claim, and desire to secure by Letters Patent, ism

In a vcabinet-desk, the draw-table E and bars h, in combination with thepivoted inclined bars l', secured to the connecting-bar 76"', and theslide-bars k', provided with clasps k, and the guides lo, as shown anddescribed.
